Abstract: 138,003. Beswick, W., and Rambush, N. E. May 24, 1919. Producers.-Water is circulated through parts of the producer requiring to be cooled. and is then brought into contact, in separate chamber, with the air blast, which is thus heated and saturated with water vapour. As shown, the water is drawn from the bottom of a coke tower b by a pump a and supplied to a water jacket c and water-cooled poker d, from which it passes through pipes g, h to the top of the tower b. The air. supplied by a pump i, ascends the tower, thus being heated and charged with water vapour, and is delivered by a pipe k to the producer. When the water becomes too impure, it may be withdrawn through a cock l and fresh water supplied through a cock m, or the water withdrawn may he purified and then returned to the tower. A by-pass n enables cold air to be mixed with the blast.

Title: Machine for jointing textile yarns or threads
Inventor: DILWORTH STANLEY
IPC: B65H69/06
Filed: 1959-04-21
Abstract: 905,893. Piecing-up or splicing yarns. WOOL INDUSTRIES RESEARCH ASSOCIATION. July 21, 1960 [April 21, 1959], No. 13488/59. Class 120 (3). In a machine or hand-tool for jointing yarns, a controlled quantity of jointing material or adhesive is automatically deposited at a position between rubbing surfaces where the yarn ends are subsequently held in mutually overlapping relationship and rolled together by two co-operating rubbing members or plates of rigid or flexible and/or compressible material which are reciprocated in opposite directions with a straight line, or slightly arcuate, motion. The machine shown enables the removal by cutting of surplus yarn between the members, location of the ends and reduction of their overlap to an appropriate length, and quick-release of the yarns by separation of the members when the joint has been completed. The rest position, Fig. 1, is with a housing 9 open and a yoke 21, carrying a dispenser 22 of adhesive, in its forward position, i.e. nearest the housing, and with a ratchet 28 on the dispenser casing 27 engaged with a detent 29. Adhesive is deposited on a plate 2 by rearwardly moving the yoke from the housing to rotate casing 27, and further rearward movement of the dispenser causes it to be lifted from plate 2 by cam faces 23. The yarns to be jointed are inserted in spring grippers 15a, 15b so that each is held by 15a at one side of the machine and 15b at the other. A knob 9a is operated to raise the housing and swing it into closed position, thereby causing pivoted blades 19 operated by levers 20 to cut unwanted ends of yarn on grippers 15b and moving grippers 15a, 15b outwards from rubbing plates 2, 3, so as to pull the cut ends into correct overlapping position wherein plate 3 rests on plate 2 and compresses the yarn ends therebetween with a pressure determined by adjustable springs 13. A finger lever 7 is operated, against restoring springs 7a, to move quadrants 6 thereby reciprocating the plates 2 and 3 (through pinions 4 and racks 5 and 12) so that adhesive is transferred to the yarns and the joint formed. Housing catches 31 are trigger-released so that spring 9b acting on linkage 10 restores the housing quickly to the open position. The jointed yarns are removed and the yoke is moved to its forward position, in which ratchet 28 re-engages detent 29, ready for the next joint, thereby returning blades 19 to their rest position.

Title: Improvements in and relating to the production of hydrogen or mixtures of nitrogen and hydrogen
IPC: C01B3/48
Filed: 1921-05-17
Abstract: By cracking a mixture of a hydrocarbon, e.g. gas oil, with air and steam in the presence of an iron-chromium alloy, a mixture of hydrogen, nitrogen, carbon monoxide, and carbon dioxide is obtained. The greater part of the carbon monoxide is then oxidized to carbon dioxide by passing the product with steam over an iron oxide catalyst at a lower temperature, the remainder being eliminated by passing the gas mixed with the requisite amount of air over a catalyst, such as the mixed oxides of iron and chromium, capable of effecting the preferential combustion of carbon monoxide in the presence of hydrogen.  The carbon dioxide is now removed in any known way, preferably by means of aqueous ammonia, leaving a mixture of hydrogen and nitrogen which may be in the theoretical proportions for the synthesis of ammonia. Hydrogen only is obtained if no air is introduced at the cracking stage.  Reference has been directed by the Comptroller to Specification 163,047.

The feed acid enters by a pipe 1 and flows upwards through horizontal cast-iron pipes 2 arranged with their return bends in end chambers 3 and 4, while the straight portions are heated by the combustion of producer gas entering at 6 and passing through holes 8 to a combustion chamber 7, where it meets secondary air entering via an inlet 9 and holes 11. The products of combustion pass over the staggered tubes in countercurrent to the acid and leave via openings 13, 14.  The setting is partly packed with refractory material.  The pipe bends may be slightly " sprung " as shown in Fig. 3, to avoid gas locks. Acid of 96-97 per cent concentration leaves by the pipe 15 while steam and any SO3 pass off by the pipe 16.  The preliminary concentration of the acid to 90-92 per cent may be carried out in a Gaillard tower, but in a preferred embodiment 65-70 per cent acid is fed into the top of a packed column up which passes the steam and SO3 produced in the pipe still, the 90-92 per cent acid emerging at the foot of the column being then passed to the pipe still for further concentration to 96-97 per cent.  Instead of horizontal pipes a vertical concentrator, Figs. 4 and 6, may be used in which finned cast-iron pipes 20 are arranged in an annular flue 21 through which combustion gases flow from the inlet 19 to the outlet 23.  Bull-nosed bricks 22 are provided adjacent to the tubes 20 to promote maximum turbulence and heat transfer.
